What a balance transfer is and how it works

A balance transfer moves debt you owe on one credit card to a different card, usually one with a lower interest rate. You do not pay off the original balance — instead, the new card's issuer pays your old card issuer on your behalf, and you then owe that new card instead.

The main reason to do this is to reduce the interest you pay while you work down the debt. If your current card charges 22% annual interest and you transfer to a card offering 0% for 12 months, you stop accumulating interest charges during that period. That gives you breathing room to pay principal instead of feeding interest.

Balance transfers are not free. Most cards charge a transfer fee — typically 3% to 5% of the amount you move. A $5,000 transfer at 4% costs $200 upfront. That fee gets added to your new balance, so you start owing more than you did before. The math only works if the interest you save exceeds the fee you pay.

Key Takeaways

  • A balance transfer moves your debt to a new card, usually to take advantage of a lower interest rate or an introductory 0% period.
  • Transfer fees run 3% to 5% of the amount moved and are added to your new balance, so calculate whether you will save money overall.
  • You initiate the transfer through the new card's issuer, who contacts your old card issuer directly — you do not send money yourself.
  • The transfer typically completes within 5 to 21 days, and you should keep making payments on your old card until the balance shows zero.
  • During an introductory 0% period, all your payments go toward principal, but interest resumes at the regular rate once the period ends.

Decide whether a balance transfer makes financial sense

Before you start the process, do the math. Write down three numbers: the balance you want to move, the transfer fee you will pay, and the interest rate on your new card.

If the new card offers 0% for 12 months, calculate how much you would pay in interest on your current card over that same year. Multiply your balance by your current interest rate and divide by 12. If that number is larger than the transfer fee, the transfer saves you money. For example: a $5,000 balance at 22% interest costs about $1,100 per year. A 4% transfer fee costs $200. You come out ahead by $900, even before you pay down any principal.

If the new card does not offer an introductory rate — if it straightforward has a lower permanent rate — the math is simpler but the savings are smaller. Compare the two interest rates and estimate how long you will carry the balance. A 1% or 2% difference matters more if you plan to pay for two years than if you plan to pay it off in six months.

Also check whether the new card has an annual fee. Some cards with strong balance transfer terms charge $95 or more per year. If you only plan to use the card for the transfer and then close it, that fee wipes out savings.

Find and open a card with a balance transfer offer

Not every credit card offers balance transfer promotions. You are looking for cards that advertise an introductory rate — usually 0% APR for a set number of months — or cards with a permanently low interest rate.

Check the card issuer's website directly. Major issuers like Chase, Bank of America, Citi, Capital One, and American Express all publish their current offers. Look for language like "0% introductory APR on balance transfers" or "balance transfer offer." The offer will specify how long the 0% period lasts (commonly 6 to 21 months) and what the regular rate will be after that.

You will need to open the new card before you can transfer a balance to it. The issuer will run a credit check and make a decision, which usually takes a few minutes to a few days. Once your account is open and active, you can request the transfer.

Read the fine print on the offer. Some cards limit how much you can transfer (for example, 95% of your credit limit). Some charge a different fee for transfers than for purchases. Some require you to transfer within a certain window — say, 60 days of opening the account — to get the promotional rate.

Request the balance transfer through your new card issuer

Once your new card account is open, contact the issuer to request the transfer. You can usually do this online through your account portal, by phone, or by mail. Online is fastest.

You will need to provide the following information about your old card:

  • The card issuer's name (for example, Chase, Citi, Bank of America)
  • Your account number on that card
  • The amount you want to transfer
  • Your name and address as they appear on the old account

The new card's issuer will contact your old card issuer directly. You do not send money yourself or authorize a payment between the two cards. The new issuer handles the entire transaction.

Ask the new issuer for a confirmation number or reference number for your transfer request. Write it down. If something goes wrong, you will need it to track what happened.

Monitor the transfer and manage both cards during the process

A balance transfer typically takes 5 to 21 days to complete. During this time, your old card still shows the full balance, and your new card shows a pending transfer. Do not assume the transfer has failed just because you see both balances.

Keep making your regular minimum payment on your old card until the balance reaches zero. If you miss a payment while the transfer is in progress, you could face a late fee and interest charges on the old card. Once the transfer completes and the old card balance shows $0, you can stop paying it.

Once the transfer lands on your new card, that balance is now your responsibility. The new card issuer will send you a bill. If the card offers an introductory 0% rate, that rate applies to the transferred balance when ready — you do not have to do anything to set up it. However, any new purchases you make on the card may be charged interest at the regular rate, even during the 0% period. Check your card's terms to see whether the 0% applies only to the transfer or to all balances.

Pay down the balance before the introductory rate ends

The whole point of a balance transfer is to use the interest-free period to pay down principal. During a 0% period, every dollar you pay goes toward the balance itself, not toward interest.

Create a payment plan. If you have 12 months at 0% and a $5,000 balance, paying $417 per month will clear the debt before the rate jumps. If you can pay more, do it — any amount you pay down before the promotional period ends is money you do not owe at the higher rate.

Mark your calendar for the date the 0% period ends. A few weeks before that date, check your card's interest rate. The issuer will explore the regular APR to any remaining balance. If you have not paid it off by then, interest charges resume and can be substantial.

If you cannot pay the balance off before the rate ends and you still have a significant amount left, you may be able to transfer again to another card with a promotional offer. This is called "balance transfer stacking" and works if you can open a new card and move the remaining balance before the first card's rate increases. However, each transfer incurs a new fee, so this only makes sense if the new card's offer is strong enough to justify it.

Understand what happens after the transfer

Once the balance transfer completes, your old card still exists but now has a $0 balance. You can close it or leave it open. Closing it when ready after a transfer can hurt your credit score slightly because it reduces your total available credit. Leaving it open costs nothing if there is no annual fee, and it keeps your available credit high, which is good for your credit score. Most people leave old cards open.

Your new card is now your active card for this debt. You will receive monthly statements showing the balance and the minimum payment due. During the 0% period, the minimum payment may be very low — sometimes just the transfer fee divided across the months. Paying only the minimum means you will not pay off the balance before the rate increases. Pay as much as you can afford.

When the introductory period ends, the regular APR kicks in. This rate varies by card and by your creditworthiness, but it is typically 15% to 25%. Any remaining balance will start accumulating interest at that rate. If you have paid off the entire transfer, you owe nothing and the rate does not matter.

Frequently Asked Questions

Can I transfer a balance if I have bad credit?

Balance transfer cards usually require good to excellent credit — typically a score of 670 or higher. If your score is lower, you may not be approved for a card with a promotional offer. Some issuers offer balance transfer cards for fair credit, but the promotional rates are shorter and the regular rates are higher. Check what you might be approved for before you explore.

What if my old card issuer refuses the transfer?

This is rare. The old issuer has no reason to refuse — they get paid in full. However, if there is a problem (for example, a fraud dispute on your old account), the transfer might be blocked. Contact your old card issuer directly to ask why. Once the issue is resolved, you can request the transfer again.

Do I have to transfer my entire balance, or can I transfer just part of it?

You can transfer any amount up to your credit limit on the new card. You do not have to move the whole balance. Some people transfer the portion with the highest interest rate and leave the rest on the old card. However, you will pay a transfer fee on whatever amount you move, so moving a small amount may not be worth the fee.

What happens if I make a purchase on the new card during the 0% period?

New purchases are usually charged the regular APR when ready, even if the transferred balance is at 0%. This means interest starts accumulating on purchases right away. To avoid confusion, use the new card only for the transferred balance and use a different card for new purchases during the promotional period.

Can I transfer a balance from one card to the same card?

No. You cannot transfer a balance from a card to itself. The new card must be from a different issuer or a different product line from the same issuer. If you want to move debt on a Chase card, you can transfer it to a different Chase card, but not back to the same account.
